In addition to being Assistant Professor in Sociology at London School of Economics, Sam Friedman is a comedy reviewer and publisher of his own arts review magazine 'Fest'. Sam describes what he has learned from his experiences, both as a reviewer and as a researcher at the internationally acclaimed Edinburgh comedy festival. Amongst other things, he tells me about comedy snobbery, why attending some comedy gigs is like sitting an exam and why some people think that laughing is not befitting of them.
